HGCN: Harmonic Gated Compensation Network for Speech Enhancement

ICASSP 2022 - 2022 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2022
Mask processing in the time-frequency (T-F) domain through the neural network has been one of the mainstreams for single-channel speech enhancement. However, it is hard for most models to handle the situation when harmonics are partially masked by noise. To tackle this challenge, we propose a harmonic gated compensation network (HGCN). We design a high-

Investigation of the switched inductor circuit for harmonics compensation [PDF]

2017 52nd International Universities Power Engineering Conference (UPEC), 2017
The switched inductor is a new circuit configuration for electronically varying the effective inductance of an inductor. In conjunction with a capacitor, filters with electronically adjustable tuning frequency can be constructed. This filter has the advantage to follow specific harmonics at the output of an inverter with varying frequency.
